RESERVE CARBID-RECEPTACLE.

Application led June 19, 1911. SeriaINO. 634,116.

To all whom it may concern.

,\V y Be it kno-wn that I, EDWIN MILLER, a citi zen of the United States, residing at Detroit, in the county of IVayne, State of hlichigan, have invented a cert-ain neY and useful Improvement in ReserveCarbid-Reccptacles, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a partof this specification.

This invention relates to reserve supply receptacles for carbid-magazines for use in connection with acetylene-generators. It is usually the case that the supply of carbid 'in the main magazine gives out at an unexpected moment When the owner of the apparatus is not in a position to immediately refill the magazine. In fact., there is a provision in most'insurance policies which prohibits the filling of acetylene-magazines at night, and even without this deterrent it is a dangerous practice to attempt refilling after dark.

It is the object of this invention to provide a timely and certain Warning of the necessity of providing lfurther carbid for the generator, and at the same time afford a suficient supply for one night, and thereby carry the user over until the nextday when he may safely refill the main magazine.

Another object of this invention is a reserve supply receptacle Which is not operable until the main supply in the magazine has been almost exhausted.

In the dravvings2-Figure 1 is a vertical section of the carbid-magazine and the reserve supply receptacle. Fig. 2, is a vertical section at right angles to the section shown in Fig. l, sho-Wing the receptacle in dumping posit-ion. tion of a modified form of reserve supply receptacle. Fig. 4, is a vertical section at right angles to the section shown in Fig. 3, and showing the carbid being dumped from the reserve receptacle.

The magazine l may be of any desired shape and is provided With an opening 2 at the top through Which it may be filled, and with a discharge opening 3 `at the bottom through Which the carbid is discharged into Fig. 3, is a vertical secr the generator (notshoivn). `The opening 3 is controlled by a cover 10 which is actu-v ated in opening and closing by a feeding apparatus (not sho-Wn) of a standard type which is Well known in the art, and Which is not shown for the reason that it is no part. of my invention.

A rod 4 is horizontally disposed arcoss the magazine l, being journaled in a bracket 5 at one side of the magazine and the bearing 6 at the other side, which is provided with pro-per packing to prevent the escape of gas. A cylindrical receptacle 8, considera-bly longer than its width, is fastened to the rod and h angs down therefrom almost to the bottom of the magazine. The center of gravity of this receptacle is somewhat below the point of its attachment to the rod. On the end of the rod 4 at the outside of the magazine a crank handle 7 is fastened. When the magazine is filled through the opening Qthe carbid enters the magazine chamber' filling both the magazine and the receptacle 8. As the carbid surrounds the receptacle 8, it 1s not possible to turn the receptacle so that it may be emptied, but when the carbid has been drawn out of the main chamberof t-he magazine to a point below the botto-1n of the receptacle 8, at Which point it is almost entirely exhausted from the magazine, the receptacle 8 is then free to be revolved by the rod 4 by the 'operators'actuating'the crank handle 7. Its contents are emptied into the main chamber of the magazine 2 Where they are ready to be drawn upon and last. until the next day, When bot-h the magazine and the reserve supply receptacle can be refilled.

In the form shown in Figs. 3 and 4 the reserve supply receptacle 8 is hung from the top of the magazine 2 by brackets 9.

The rod 4 runs through the disk 11 that forms the bottom of the receptacle 8. This disk is adapted to be turned by the rod opening and closing the opening at the bottom of the receptacle. When the main chamber of the magazine and the receptacle are both filled, it is impossible to turn the crank 7 because the disk ll is firmly held by the surrounding carbid. However, when the storage in the mainchamber is reduced below the path of travel of the disk, when it is swung by the rod 4, the contents of the reits top to the rod, the said bucket beingvcompa-ratively-deep so that its loWel` end reaches nearly to the outlet of the main magzizine, Y10 and means by Which'the xjod may be rocked.

In testimony whereof, I sign this specification in the presence of tyvo Witnesses.

EDWIN MILLER.
